文摘

Solid-state electrolytes are being intensively explored as the key to develop all-solid-lithium secondary batteries which present safety advantages over present liquid Li-ion technology. To validate the use of the Li₆PS₅Cl-based solid electrolyte obtained by high energy ball milling, all-solid-state batteries using LiCoO₂ and Li₄Ti₅O₁₂ as active material (AM) have been realized. The optimization of the electrode composition led to a maximum of 46 and 27 mAh per gram of composite for LiCoO₂ and Li₄Ti₅O₁₂-based half-cells respectively. The assembled all-solid-state LiCoO₂/Li₆PS₅Cl/Li₄Ti₅O₁₂ battery presents a sustainable reversible capacity of 27 mAh per gram of AM and a coulombicic efficiency close to 99 % .
